Well, first of all, I think that such moves should have been made a long long time ago, like kicking that psycho Mihajlovic off the national team for all the disgrace that he did when he played in crucial games.
The problem that I see is that even though Kezman is not playing for Chelsea, his team is MUCH MUCH better than Serbia's national team... so just because he's not in their starting rotation it doesn't mean he's out of shape. On the other hand, Savo did a lot for the national team, but I agree that we should test some new blood out. If they fail, then we can always bring the vets back.
